Every cell in the human body faces a chronic challenge: protecting its DNA. Whenever cells divide, their genetic material must be copied accurately. But DNA is continuously under attack, and when damage goes unrepaired, it can threaten genome stability and contribute to the progr

Brain cells meant to protect us may be fueling cognitive decline

Scientists have uncovered a surprising cause of age-related cognitive decline involving brain cells previously thought to be entirely beneficial. As these cells become dysfunctional, they can produce abnormal amounts of myelin, disrupting nerve fibers and potentially contributing
